SPINNING JET 0R NOZZLE FOR THE MANUFACTURE OF ARTIFICIAL SILK, ETC.

- Application filed August 26, 1921. Serial No. 495,791.

To all whom it may concern:

Be it known that we, Doctor -CAMILLE lDREYFUS, a citizen of Switzerland, and GUY LEONARD, a British subject, now residing at Cumberland, Maryland, have invented acertain new and useful invention in Spinning Jets or Nozzles for the Manufacture of Artificial Silk, Threads, Filaments, Artificial Horsehair, Textiles, etc., of which the following is a description.

The spinning jets or nozzles for the manufacture of artificial silk, threads, filaments, artificial horsehair, textiles, etc. which have been and are now actually used are mostly made out ofmetals of a certain thickness, and the greater the pressure such a jet or nozzle is exposed to, the thicker, of course, the metal has to be, in which the holes are drilled to withstand the pressure. We have now found that we get considerably better results and that we canuse for any pressure or any spinning solution a very thin sheet containing the spinning holes, which sheet is made of metal or other appropriate material and called the spinning sheet, having holes drilled of size and number necessary to give the desired threads or filaments. This spinning sheet-may be a solid sheet, or perforated sheet, or washer, or ring, etc. This spinning sheet can be secured between two reinforcing plates of any desired thickness by means of a screw, bolt or any other means of fastening, these having openings in a position corresponding to the holes in the spinning sheet, but of a size somewhat larger than the holes in the spinning sheet. Theseopenings or holes in the reinforcing plates maybe countersunk on the opposite side to the point of contact with the spinning sheet. Any othersuitablecombination between spinning sheet and reinforcing plate may be used, for instance, the spinning sheet can be fixed or screwed on only one reinforcing plate, this being the sup-porting plate, or anyother suitable combination may be arranged.

. A great number of the spinning jets used atthe present time are manufactured out of precious metals, like platinum, gold, silver, or other alloys, therefore, apart from the advantage which our new spinning jet combination ives for the spinning of artificial silk, arti cial horsehair, threads, filamentah reinforcing plates tificial si toning th textiles, etc, it reduces the cost of the spinning jets to a very great extent.

' In the drawings: I Figure 1 is a section through one form of the invention.

Figure 2 is a section through a modified form.

A splinning plate 4 which may be made of thin s eet material is provided with holes 5 of any desired number and size. This plate is clamped in position between an upper reinforcin tapered openings and a lower reinforcing plate 8 provided with tapered openings 9. Thesetapered openings are slightly larger at their smallest portions than the openings in the spinning plate 4.

The plates,4, 6 and 8 may be fastened to gether or held in any desired manner.

In the modification shown in Figure 2, the upper reinforcing plate is omitted and the spinning plate 4: is held in operative rela- 75 cious metals .are used. or their manufacso ture, and at the same time any desired pres sure may be employed for forcing the solution through the spinning openings.

What we claim is:

1. A spinning jet for the spinning-of aras k or the like, comprising a thin .metal sheet provided with suitable spinning holes, reinforcing plates between which the thin sheet is secured, said reinforcing plates being provided with holes corresponding to. so

the spinning holes in the thinesheet but .Whichare larger and countersunk from the outside to the point of contact with the thin.

2. A spinning jet for the spinning of artificial silk or the like, comprising a thin metal sheet provided with suitable spinning holes, ,a reinforcing plate on at least one side of the thin sheet and provided with new holes corresponding to the spinning holes in J the sheet but which are larger and are coun H tersunk from the outside to thepoint of contact with the thin sheet, and means for fas- 3. A spinning jetfoi' the spinning of arplate 6 provided with e sheet andplate. firmly together. peg

I being tificial silkor the like, comprising a thin sheet provided with suitable s inning holes, a reinforcing plate on one si e of the thin sheet and provided with holes corresponding to the spinning holes in the sheet, and means for fastening the sheet and plate firmly to gather.

' A. A spinning jet for the spihnin of ar- =tificial silk or g 10 thelike, comprising a thinmetal sheet provided with suitablespinning holes, reinforcing plates between which the thin sheet is secured, said reinforci plates provided with holes correspon ing to, but arger than, the spinning holes in .the sheet, and means for fastening said sheet and plates firmly together.
